Video: Dolphins Mike Pouncey returns to field

Multiple hip surgeries, countless hours of rehabilitation, a stem cell treatment, it’s all worn on Miami Dolphins center Mike Pouncey, who conceded Thursday there were days last season he felt he could not walk. And then Pouncey ran. And he smiled. And he put on a Dolphins helmet. The Dolphins opened training camp on Thursday and although he was not a full participant, the leader of Miami’s offensive line, and one of the leaders of the team, had been cleared by doctors for some football activity.
